As you enjoy the psychoactive effects of weed, there comes the lingering after-effect.

Weed Hangover

Cannabis connoisseurs have relied on the effects of medicinal marijuana for recreational purposes and even medicinal marvels. However, a shadowy aftermath may also leave the user’s body feeling a little peculiar. Once the hangover happens – do you know how to ease its effects? How long do weed effects last?

A weed hangover is the lingering after-effect of consuming or smoking too many marijuana substances. What’s a hangover feel like? It can make you feel lethargic, have a foggy mind, mild nausea, and dry eyes. Here are some more of the signs of cannabis hangover:

  • Dry Mouth and Thirst – Dehydration may also occur, leading to a dry mouth and increased feeling of thirst.
  • Mood Changes – Overdosing can make some individuals irritable, anxious, or more emotionally sensitive.
